HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 668,856, dated February26, 1901.

Serial No. 32,422- (No model.

To (all whom it may concern.-

Be it known that I, JULES LEVRECHON, of Auburn, in the county of Cayuga,in the State of NewYork, have invented new and useful Improvements inHeating Apparatus, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

This invention relates to heating apparatus, and has for its object theproduction of a simple and practical device whereby a flowing current ofwater may be readily heated in transit and the products of combustionutilized for cooking or other purposes.

To this end the invention consists in the combination, construction, andarrangement of the parts of a heating apparatus, as hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective view of a bath-tuband my improved heater, showing the applicability of said heater forheating a current of water passing therethrongh and discharging into thebath-tub. Fig. 2 is a vertical sectional view through the center of theheating apparatus seen in Fig. 1. Fig. 3 is a transverse sectional viewtaken on line 3 3, Fig. 2.

My invention is designed to be connected to any cold-water-supplyconduit for the purpose of heating the water in its transit through saidheater and discharging the same into any desired receptacle; and itconsists of outer and inner receptacles l and 2, telescoping with eachother, the outer section forming, essentially, the combustion-chamber ofthe heater and the inner receptacle being adapted to receive the coldwater.

The outer section 1 may be of any desired form or construction, and itpreferably consists of an outer cylindrical shell having a bottom wall 3and an opening 4 in its upper end for receiving the inner receptacle 2.The bottom wall 3 is provided with asubstantially central aperture 5 andan upwardly-extendin g water-conduit 6, having its lower end surroundingthe aperture 5 and secured to the bottom Wall 3 and its upper end openand having its upper face disposed in substantially the same plane asthe upper end face of the inclosing walls of said outer section.

The inner section 2 is detachably supported upon the outer section 1, isadapted to receive the cold water, and preferably consists of acylindrical shell having itslower portion formed of less diameter thanits upper portion and arranged to telescope within the outer section andits upper portion formed of greater diameter than the outer section forforming an annular bearing-face 7, adapted to rest upon the upper endface of the Wall of the outer receptacle for supporting the innerreceptacle in its operativeposition. This inner section is provided withlower and upper end walls 8 and 9, having apertures 10 and 11, which areconnected to each other by suitable heat-flues 12, having their lowerends surrounding the apertures 10 and secured to the bottom wall 8 andtheir upper ends surrounding the apertures 11 and soon red to the upperwall 9. The lower reduced portion of the inner cylinder 2, between thebearingface 7 and the bottom wall 8, is preferably formed of less lengththan the outer section 1 for forming a combustion-chamber in the base ofthe said outer receptacle. The tubes 12 extend lengthwise through theinterior of the section 2, their lower ends communicating with thecombustion-chamber and their upper ends discharging the heated air orgases above the upper Wall of the said inner receptacle.

The bottom wall 8 of the inner receptacle is provided with asubstantially central aperture 13, which is usually of greater diameterthan the water-tube 6 for receiving said water-tube when the sectionsare assembled.

14 is a suitable conduit having its lower end surrounding the opening 13and secured to the bottom wall 8 and its upper end extending slightlyabove the upper end face of the tube 6 and provided with an end wall 15,adapted to rest upon the upper end face of said tube 6. This conduit 14:is also of greater diameter than the conduit 6 for forming a spacebetween said conduits for receiving the heated products of combustion.The means for supplying water to the inner receptacle 2 usually consistsof a conduit 16, having its lower end arranged in proximity to the bottom wall 8 and its upper end extended through an aperture 17 in theupper wall of the receptacle 2 and connected to any suitable source ofwater-supply.

Any suitable fuel may be used within the combustion-chamber of the outersection 1 for heating the water within the receptacle 2; but Ipreferably employ an ordinary gas-burner 20, supported within the baseof the combustion-chamber of the outer section and connected by a pipe21 to any desired source of gas-supply.

Arranged within the combustion-chamber, and preferably between the wallsof the inner and outer receptacles, is a draft-pipe 21, having its lowerend communicating with the combustion-chamber and its upper endcommunicating'with the atmosphere in proximity to the upper end of theouter chamber 1.

The portion of the inclosing wall of the inher chamber adjacent to thedraft-pi pe is preferably depressed inwardly for forming a recess 23,which receives the draft-pipe 22 and permits the same to be removed whendesired. The upright portion of the gas'snpply pipe 21, which isconnected to the burner, is usually arranged within the draft-pipe 22and extends laterally through an aperture 24 in the upper end of theinclosing wall of the receptacle 1, said aperture also forming a meansfor communication between the atmosphere and the upper end of thedraft-pipe. The upper portion of the inner receptacle 2 is provided withan outlet-opening 25and a downwardly-deflected nipple 26, communicatingwith the opening 25,for discharging the heated water from the receptacle2.

At Fig. 1 I have shown my improved heater in position for supplyingheated Water to an ordinary bath-tub A, which is provided with awater-supply pipe at and an overflow-pipe a. When used in thisconnection, the heater is usually supported upon the bottom wall of thebathtub, and the overflow-pipe a is formed of less height than thedistance between the bottom wall of the bath-tub and the opening 24 ofthe heater in order that the Water discharged from the heater andflowing into the bath-tub may be prevented from flowing into thecombustion-chamber of the heater through the opening 24. The watersupplyconduit a of the bath-tub is connected by a conduit 27 to the conduit16, and the gas-feed pipe 21 is connected by a conduit 28 to a suitablegas-supply conduit B.

This heater is not only adapted for use in speedily and efficientlyheating or boiling water during its passage through the inner chamber 2,but may also be used for cooking purposes simultaneously With its use asa waterheater. For this latter purpose the upper end wall of the innersection 2 is formed substantially flat for receiving and supporting anyform of cooking utensil (not illustrated) in the path of the escapingproducts of combustion through the fines 12. In fact, a'sec- 0ndWater-heater may be thus superimposed above the flues 12 and providedwith inlet and discharge openings for receiving and discharging waterinsubstantially the same manner and for the same purposes as described forthe receptacle 2.

In the operation of my invention the gas escaping through the burner 20within the combustion-chamber of the heater is ignited and the productsof combustion pass upwardly through the tubes 12. The water is admittedto the inner receptacle 2 through the supply-pipe 16 and entirelysurrounds the tines l2 and central tube 14. The water is thus heated bythe products of combustion in said lines 12 and the tube 14 and isdischarged through the opening 25 into the bathtub or other receptacle.The heater is usually supported a slight distance above the bottom wallof the bath-tub or other receptacle upon suitable supports 30 andpermits the water to entirely surround the lower portion of the heater,and it rises within the central tube 6, thereby additionally heating thewater which is within the bath-tub or other receptacle in which theheater is placed. When the heated water rises to a certain heightbeneath the opening 24, it overflows into the overflow-conduit a andprevents the water from overflowing into the combustionchamber.

The operation of my invention will now be readily understood uponreference to the foregoing. description and the accompanying drawings,and it will be noted that considerable change may be made in the meansfor supplying heat to the combustion-chamber and that other changes maybemade in the detail construction and arrangement of the parts ofmyinvention Without departing from the spirit thereof. Therefore I donot limit myself to the precise construction and arrangement shown anddescribed.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
